[Termes IGN] SIG participatifRésumé : (Auteur) Collaborative GIS has emerged as an efficient, spatial decision-making tool, especially when 3D GIS models are integrated. While centralized architecture is still dominating the design and development of such tools and/or systems, alternative architecture, such as peer-to-peer (P2P), and hybrids have been given increasingly more attention in designing more scalable and efficient systems. This paper presents a conceptual hybrid system architecture for the development of integrated, synchronously collaborative environments with 3D GIS tools for group decision-making and 3D information sharing. In this paper, we discuss the major design issues related to such an architectural design and identify the spatial requirements of synchronous collaborative 3D GIS. A hybrid architectural model integrating centralized and replicated computing architecture is then designed to address the identified requirements. The proposed architecture was tested using data/message flow models developed to facilitate component-based collaborative 3D GIS systems. The results show that collaborative 3D GIS require collaboration computing different from that applied in generic GIS systems, and that a component-based development approach can lead to more light-weight systems.

[Termes IGN] Time-geographyRésumé : (Auteur) Today, the opportunity for potential human activity has gone beyond physical space to virtual space. Based on a proposed conceptual framework that models the relationships between physical and virtual spaces, this paper presents an attempt to adjust the space-time prism concept of Haumlgerstrand's time geography to identify potential activity opportunities in virtual space, focusing on the virtual space access channels available in physical space. A three-dimensional (3D) spatio-temporal Geographic Information System (GIS) design has been developed in this research to accommodate the adjusted space-time prism concept to support the representation, visualization, and analysis of potential human activities and interactions in physical and virtual spaces using the prism representation. Following the design, a prototype system has been successfully implemented in a 3D GIS environment. Such a system can provide powerful analytical tools for studies related to potential human activities and applications such as location-based services (LBS) and accessibility analysis in the information age.

[Termes IGN] voie de communicationRésumé : (Auteur) The existing road-network models based on the 2D link-node of roadway centrelines have inhibited lane-oriented network flow analysis and multi-dimensional inventory management in complicated 3D urban environments. This paper proposes a hierarchical lane-oriented 3D road-network model (HL-3DRNM), with a unified modelling language (UML) diagram. HL-3DRNM is a non-planar topological model with the support of a 3D lane ribbon cartographic display, which is characterized by: (1) multiple topological and cartographic representations and various abstraction levels (street, road segment, carriageway and lane); and (2) referenced multi-dimensional road information (point, line, area and volume) at lane level. HL-3DRNM provides solid mathematical foundations for a more detailed inventory management, effective network analysis and realistic navigation in the increasingly complicated 3D urban transportation systems.

[Termes IGN] SIG participatifRésumé : (Auteur) Collaborative GIS provides a spatially referenced negotiation environment for decision makers to put forward their perspectives, discuss their differences, and, ultimately, make decisions. Recent research has focused on enabling the representation of, and selection from among, different opinions, while discussion among people has been ignored. This paper reports on a discussion process aimed at reconciling inconsistent perspectives in distributed workgroups. The Speech Act Theory (SAT) of Austin was extended to define both non-spatial and spatial speech acts in the context of a negotiation. A coordination process was modeled by these speech acts. Then, inconsistent perspectives were reconciled using detection of inconsistency, or initial integration of perspectives, or reconciliation of collaborators. The method we propose makes it possible to effectively describe the speech acts and use them to naturally represent the reconciliation process. A prototype system based on this approach was implemented in experiments. Their results demonstrate that a good abstraction of the negotiation process will facilitate the coordination of discussion among people and provide a criterion for system designers.
